August Lütgens (16 December 1897 – 1 August 1933) was a communist activist who spent the 1920s exiled in the Soviet Union. On returning to Germany in 1930 or 1931 he became a leading member of the paramilitary "Red Front-Fighters" ("Roter Frontkämpferbund" / RFB) in the politically volatile Hamburg region. In 1932 he was involved in the Altona Bloody Sunday street battle and, following the National Socialist power grab at the start of 1933, he became a victim of "Nazi justice". On 1 August 1933 August Lütgens was executed: four men were convicted and executed at the same time, but Lütgens was identified at the time as the leading figure among them, and of the four cases, it is the one involving Lütgens that has received the most coverage subsequently.
